2014-07-30[media] au0828: add support for IR on HVR-950QMauro Carvalho Chehab
HVR-950Q uses an I2C remote controller at address 0x47 (7-bits notation). Add support for it. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] au0828: improve I2C speedMauro Carvalho Chehab
Commits 21dc61d3c0a4 and 7a1dd50b89d4 reduced the board I2C speed to 20 MHz by default, due to a I2C stretch issue: while xc5000 uses i2c stretch when a command is sent to it, au0828 doesn't support this feature. However, this is needed only for Xceive tuners. The other I2C devices can work at the max speed. So, revert the workarounds at board level, handling it at I2C level, only when talking with xc5000.

2014-03-11[media] au0828: fix i2c clock speed for DViCO FusionHDTV7Joonyoung Shim
DViCO FusionHDTV7 device that use au0828 can fail to communicate with xc5000 using i2c interface because of high i2c clock speed - i2c clock stretching bug. It causes to fail xc5000 firmware loading normally at the current driver. Already this problem fixed as changing to low i2c clock speed at HVR-950q device, also DViCO FusionHDTV7 device can solve it as using low i2c clock speed - 20KHz.

2014-02-28[media] au0828: rework GPIO management for HVR-950qDevin Heitmueller
Restructure the way we bring the various GPIOs out of reset. In particular: 1. we only need to setup the GPIOs as outputs once 2. there's no point in writing 0x40 to register 0x00 since that's the EEPROM write protect and already it's configured as an input 3. Separate out the act of enabling the power supply and bringing the tuner and demod out of reset. If you don't then the chip may not be properly enabled (as the power supply is still ramping up when the chip comes out of reset). This can result in probing failures.

2012-12-27[media] au0828: Replace memcpy with struct assignmentEzequiel Garcia
This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Ezequiel Garcia <elezegarcia@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-12-17[media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2Michael Krufky
This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog video capture support and depends on VIDEO_V4L2 itself. With VIDEO_AU0828_V4L2 disabled, the driver will only support digital television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2 enabled, the driver will be built with the analog v4l2 support included. By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to preserve the original behavior.
